You can try setting the RETRIES value to be higher. After 10 retries the software steps the head forwards/backwards to try to "scrub" the surface. It could be that the disks are just dirty. Also keep in mind that you should be cleaning the heads of the disk drive you are using with SCP just about every time you make a copy or image. It does make that much difference because oxide comes off easily due to the age of the disks. Cleaning the heads is not optional.
